At what resolution? It all depends on the total bandwidth needed for the settings you want to use.

Passive adapters like the one in that link will limit you to single link DVI bandwidth, which is generally 1920x1080@60Hz. To go higher than that, you'll need an active adapter like this one, which will support dual link DVI for a maximum of 1920x1080@120Hz or 2560x1600@60Hz :

http://www.amazon.com/Accell-B087B-007B-DisplayPort-Dual-Link-Adapter/dp/B00856WJH8/ref=sr_1_10?ie=UTF8&qid=1362079014&sr=8-10&keywords=displayport+to+dvi+converter

It depends a lot on the display, but you can also get some extra bandwidth by setting a custom resolution and manually changing the timing to CVT Reduced Blank. Doing this can get you anywhere up to a 40-50% increase in total pixel throughput.

More than likely though, you'll need the more expensive active adapter with dual link support to run your display at full spec unless it's 720p or lower.

Thanks for the feedback i tried that with an active adaptor i bought about a year ago when i was running eyefinity with my 6990 quadfire setup and i tried it the other night and it said it was still limited to 60hz. Ill have a proper look tonight if not i guess i will have to wait for another Gtx Titan to run 3x 27" Displays at 144hz. Also with the active adaptor it would still be limited to 120hz @ 1920x1080.

Did you solve this?

I am currently looking adding a third Asus 278HE/R at 144Hz with one GTX Titan card. This means one monitor needs to connect with DisplayPort.

Please share your solution.
